Data corruption is the damage of data due to various software or hardware problems. Once a file gets damaged, it will no longer work accurately, so an application will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, which makes it a serious problem for web hosting servers as failures are more likely to occur on bigger hard drives where considerable volumes of information are placed. When a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as an ordinary one and will be copied on all drives, making the harm permanent. A huge number of the file systems which run on web servers these days often cannot detect corrupted files in real time or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Website Hosting

If you host your websites in a shared website hosting account with our company, you won't have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the leading-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. All information that you upload will be stored in a RAID i.e. simultaneously on many SSD drives. A lot of file systems synchronize the files between the different drives using such a setup, but there's no real warranty that a file won't get corrupted. This can occur during the writing process on each drive and afterwards a corrupted copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all of the drives instantly and in the event that a corrupted file is found, it is replaced with a good copy with the correct checksum from some other drive. That way, your data will stay intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any risk of files getting corrupted silently because the servers where your semi-dedicated server account will be created use a powerful file system called ZFS. Its advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we store all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. In case there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens in real time, there's no chance that a damaged copy could remain on our servers or that it can be copied to the other hard disks in the RAID. None of the other file systems employ such checks and what's more, even during a file system check right after an unexpected electrical power failure, none of them will detect silently corrupted files. In comparison, ZFS will not crash after a blackout and the continual checksum monitoring makes a lenghty file system check obsolete.
